so how much for the doofer thingy then??
Nothing if you apply via the link in my first post. This company (Alis) only operates the A28 between Alencon and Rouen but are doing the doofers for free and they cover the whole network (plus Alis car parks, oddly enough!) No monthly charges either. I have never bothered before either but as there's no financial outlay (except when you use it),it struck me finally as being worth having. No way was I ever going to pay a monthly fee as most of the other suppliers do. Hence my post.
